H$_2$ Activation at Copper for the Synthesis of Hydride Complexes

International audienceAs hydrogen can be a green reductant, the hydrogenation of organic compounds is a key reaction both in industry and for fundamental knowledge. Copper(l) catalysts have been widely used to activate H$_2$ in particular with the aim of c=o bond hydrogenation Even if mechanistic studies always point out the importance of copper hydride complexes either as active catalysts or intermediates, only a few were fully characterizedYl To sort out this dualism and in order to further understand copper-catalyzed c=o bond hydrogenation, we sought to synthesize copper(l) hydride complexes with molecular H$_2
